Tomas Lindquist Olsen 928f7d4de5 [svn r296] Removed: the 'suite' dir, it never took off!
Fixed: foreach statement, key-type checks were buggy.
Fixed: setting LLVMDC versions on the command line is now an error.
Fixed: array compare runtime had incorrect param attrs on call.
Fixed: index expressions on dynamic array slices w/o storage was broken.
Fixed: scope classes had incorrect finalization in some cases.
Fixed: when outputting !ClassInfoS !OffsetTypeInfoS, static class members were trying to be included, crashing the compiler.
Fixed: calling LLVMDC with -inline but not any -O option caused assertion failure.
Changed: the runtime now uses a single interface to "get" to !TypeInfoS, part of eliminating duplicate !TypeInfo codegen.
